Precise in curves, reliable on the straight
New at norelem: linear roller guides
Linear guides are used in many areas where bodies need to be moved with as little force and friction as possible, for example in the packaging or foodstuff industry or for in-frame doors in ships or trains. norelem now also offers linear roller guides, divided into four product families.
The linear roller guides offered by norelem include straight and curved linear guide rails made of bright, hardened steel and two variants of the matching roller carriages. The linear roller guides are available in two sizes, which differ in terms of the height and width dimensions of the linear guide rails.
Linear guide rails
norelem offers its linear guide rails with and without slots. In the variant with a double-sided slot, rails can be easily assembled using a countersunk parallel key. This allows the rails to be screwed directly onto a flat surface. In addition, precise alignment using a parallel key makes it easier to pass over the butt joint. All linear guide rails with keyways can be combined as required to create complex geometries from curved and straight linear guide rails. In the versions with a slot, the parallel keys are included in the scope of delivery, as are press-in plugs that cover the screws in the rails and protect them from dirt and foreign bodies. norelem also offers the straight linear guide rails without a slot and in three standard lengths of 500, 1,000 and 2,000 mm, and also in lengths of up to 4,000 mm on customer request.
The linear guide rails can be screwed on from above and can be fitted with one or more roller carriages.
Roller carriages
The roller carriages 21350 have a simple mechanism that permits a compensation of ca. 0.05 mm. Therefore, only straight linear guide rails can be traversed. The compensating mechanism of the roller carriages 21351 permits a tolerance range of ca. 0.5 mm. This enables the carriage to travel on straight and curved linear guide rails. Here, the maximum acceleration is 50 m/s² and the maximum traversing speed is 5 m/s. Thanks to the integrated, one-sided pre-tensioning mechanism, the rollers always adapt to the rail contour. This enable play-free traversing on straight tracks and curves with constant displacement resistance and wear on the roller guides is also reduced. There is no need to adjust the rollers to the rail width using an eccentric pin. The roller carriages can simply be pushed onto the rail. Here, all carriages travel evenly and without the rollers slipping on the rails.
